This standard applies to the use of pulse pressure to withstand high pressure hydraulic hoses and hose assemblies. This standard gives the hose and hose assemblies Flexing both methods, the actual test pressure pulses are given in ISO 6803.

Rubber and plastics hoses and hose assemblies with wire reinforcements.Hydraulic impulse test with flexing ICS 23.040.70 G42 National Standards of People's Republic of China Replacing GB/T 14904-1994 Steel Reinforced Rubber and Plastic Hoses and Hose Assemblies Flexion hydraulic pulse test (ISO 6802..2005, IDT) 2011-12-30 release 2012-10-01 implementation General Administration of Quality Supervision, Inspection and Quarantine of the People 's Republic of China China National Standardization Management Committee released ForewordThis standard is drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 14904-1994 "Steel wire reinforced rubber, plastic hose and hose assembly flexion hydraulic pulse test". The main technical changes compared to GB/T 14904-1994 are as follows. - Added test method 2 (see Chapter 3); - Added method of use (method 1 or method 2) in the test report (see Chapter 7, Chapter 7 of the.1994 edition); - modified the scope of application (see Chapter 1,.1994, Chapter 1); --- modified the minimum bending radius, the letter of the outer diameter of the hose (see Chapter 4,.1994, Chapters 3 and 4); - the results are removed (see Chapter 6 of the.1994 edition). This standard uses the translation method equivalent to ISO 6802..2005 "wire reinforced rubber and plastic hose and hose assembly crank hydraulic Pulse test ". And this standard in the normative reference documents have a consistent relationship between the Chinese documents are as follows. Rubber or plastic hoses and hose assemblies - Non - flexural hydraulic pulse test (ISO 6803..1994, IDT). This standard is proposed by the China Petroleum and Chemical Industry Association. This standard is nationalized by the National Rubber and Rubber Products Standardization Technical Committee Hose Subcommittee (SAC/TC35/SC1). The drafting of this standard. Shenyang Rubber Research and Design Institute, chemical industry hose and tape products Quality Supervision and Inspection Center, Ningbo Feng Mao far East Rubber Co., Ltd. The main drafters of this standard. Cao Zhibin, Zhang Jiankun, Cao Youhua. Steel Reinforced Rubber and Plastic Hoses and Hose Assemblies Flexion hydraulic pulse test1 ScopeThis standard specifies the wire reinforced rubber and plastic hose and hose assembly crank hydraulic pulse test method. This standard applies to high pressure hydraulic hoses and hose assemblies that withstand pulsed pressure when in use. This standard gives two buckling methods for hose and hose assemblies. The actual pulse test pressure is given in ISO 6803.2 normative reference documentsThe following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this article Pieces. For undated references, the latest edition (including all modifications) applies to this document. ISO 6803 Rubber or plastic hoses and hose assemblies No Rubber brake test (Rubberorplasticshosesand hoseassemblies-hydraulic-pressureimpulsetestwithoutflexing)3 test methodTwo method of flexing is given. Method 1 uses the rotary manifold shown in Figure 1; method 2 uses the horizontal sliding manifold shown in Fig. When production When the standard is not specified, the method 1 is used.4 equipmentThe test equipment is a pulsed test rig with a flexure device, which can be mounted on the test bench and can provide a test piece as shown in Figure 1 or Figure 2 movement. The test bed consists of a fixed manifold and a movable manifold which can be rotated (see Figure 1) or horizontally figure 2). The fixed manifold centerline is equal to the center of rotation of the rotating manifold and is equal to the center of the horizontal reciprocating manifold. Activity manifold Is driven by gear so as to always be parallel to the fixed manifold. The number of active maneuvers per minute rotation or reciprocating cycles should be pulses per minute The number of cycles of 34% to 38%, that is, within a given time generated by the number of flexion cycle and the number of pulse cycles into a ratio. The distance from the vertical centerline of the pipe joint fixed manifold to the center of rotation of the movable manifold or the center of the reciprocating movement is l. Any situation , The hose is subjected to a reverse bending motion so that its inner radius is less than the minimum bending radius, and the radius near each pipe joint is greater than the maximum Small bending radius. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 14904-2011_English be delivered?Answer: Upon your order, we will start to translate GB/T 14904-2011_English as soon as possible, and keep you informed of the progress.
